Although we had encountered but very few buffalo since we left Spring Valley, they now began to make their appearance again, though not in very large droves; together with the deer and the fleet antelope, which latter struck me as being much more tame in this wild section of the Prairies than I had seen it elsewhere. The graceful and majestic mustang would also now and then sweep across the naked country, or come curvetting and capering in the vicinity of our little caravan, just as the humor prompted him. But what attracted our attention most were the little dog settlements, or, as they are more technically called, 'dog towns,' so often alluded to by prairie travellers. As we were passing through their 'streets,' multitudes of the diminutive inhabitants [Pg119] were to be seen among the numerous little hillocks which marked their dwellings, where they frisked about, or sat perched at their doors, yelping defiance, to our great amusement--heedless of the danger that often awaited them from the rifles of our party; for they had perhaps never seen such deadly weapons before.
On the 5th of June, we found ourselves once more travelling on a firm rolling prairie, { 33} about the region, as we supposed,[86] of the boundary between the United States and Mexico; when Lieut. Bowman, in pursuance of his instructions, began to talk seriously of returning. While the wagons were stopped at noon, a small party of us, including a few dragoons, advanced some miles ahead to take a survey of the route. We had just ascended the highest point of a ridge to get a prospect of the country beyond, when we descried a herd of buffalo in motion and two or three horsemen in hot pursuit. "Mexican Ciboleros!" we all exclaimed at once; for we supposed we might now be within the range of the buffalo hunters of New Mexico. Clapping spurs to our horses, we set off towards them at full speed. As we might have expected, our precipitate approach frightened them away and we soon lost sight of them altogether. On reaching the spot where they had last been seen, we found a horse and two mules saddled, all tied to the carcass of a slain buffalo which was partly skinned. We made diligent search in some copses of small growth, and among the adjacent ravines, but could discover no further traces of the fugitives. The Indian rigging of the animals, however, satisfied us that they were not Mexicans.
